Happy Trails - S1-E9
Revealing mistake: In the beginning of the episode, Manfredi shoots the man, which ends up being the crime he is sent away 25 years for. As Manfredi walks out of the burning building and the cops tell him to put up his hands, you can easily see that it is a stunt double and not Sylvester Stallone. He definitely had a way smaller build and looked shorter.
